Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to hot presses. Background Technology

[0002] Hot presses are key pieces of equipment widely used in composite material processing, insulation material molding, and multilayer material pressing. They achieve material curing, bonding, or densification through the synergistic effect of heating and pressurization. In fields such as power electronics, aerospace, and automotive manufacturing, the performance of insulating materials directly affects the safety and reliability of equipment, and hot pressing is a core means of improving the mechanical strength, dielectric properties, and interfacial bonding quality of insulating materials.

[0003] Currently, the hot pressing of insulating materials mainly relies on manual or semi-automatic feeding, which has the following problems: insulating materials are usually large in size and heavy in weight, making manual handling labor-intensive and prone to damage or contamination due to improper operation. When placing materials manually, it is difficult to ensure accurate alignment, which can easily lead to misalignment, resulting in uneven edges or interlayer misalignment of the pressed product, affecting the insulation performance. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a hot press, including a hot press chamber 1. A steam inlet 23 is fixedly connected to the top of the hot press chamber 1. A bearing plate 2 is fixedly connected to the lower right side of the hot press chamber 1. A support leg 3 is fixedly connected to the lower side of the hot press chamber 1. A limit plate 4 is fixedly connected to the upper side of the bearing plate 2. A left-right movable feeding plate 5 is provided inside the limit plate 4. A push plate 22 is fixedly connected to the upper side of the feeding plate 5. Fixing pins 6 are fixedly connected to both the front and rear sides of the left end of the bearing plate 2. A rotating ring 7 is rotatably connected to the outside of the fixing pins 6. The outside of the rotating ring 7 is fixedly connected to... A spring 8 is provided. A rotating plate 9 is rotatably connected to the right side of the hot press chamber 1. The right side of the rotating plate 9 is fixedly connected to the end of the spring 8. A fixed frame 18 is fixedly connected to the lower side of the bearing plate 2. A threaded rod 19 is rotatably connected inside the fixed frame 18. A threaded plate 20 is threadedly connected to the outside of the threaded rod 19. The top of the threaded plate 20 is fixedly connected to the lower right side of the loading plate 5. A motor 21 is fixedly connected to the right end of the fixed frame 18. The drive end of the motor 21 is fixedly connected to the top right end of the threaded rod 19. An adjustment groove 17 for the left and right movement of the threaded plate 20 is provided in the middle of the bearing plate 2.

[0025] The operator lays the material to be pressed flat on the loading plate 5, and places partitions 16 between the material layers as separators to ensure that the multiple layers of material maintain their relative positions during the pressing process. The partitions 16 are made of a material with good thermal conductivity. After starting the motor 21, the threaded rod 19 rotates clockwise, driving the threaded plate 20 to move to the left along the adjusting groove 17. Since the threaded plate 20 is fixedly connected to the loading plate 5, the loading plate 5 slides to the left accordingly. The pushing plate 22 simultaneously pushes the material into the hot press chamber 1, and the left end of the material contacts the rotating plate. At 9 o'clock, the rotating plate 9 is pushed to rotate, and the spring 8 is stretched. When the material is fully entered into the thermostatic chamber 1, the elastic restoring force of the spring 8 pulls the rotating plate 9 back to the vertical position with the limiting plate 4. It is restricted by the limiting plate 4 and cannot rotate outward. The motor 21 reverses and the threaded rod 19 drives the feeding plate 5 to return to the right end of the bearing plate 2. At this time, the rotating plate 9 cannot rotate outward due to the obstruction of the limiting plate 4, ensuring that the material stays stably in the thermostatic chamber 1, completing the feeding operation, thereby improving the feeding efficiency and the stability of the feeding.

[0026] Reference Figure 1 , Figure 3 and Figure 5 Limiting rods 10 are fixedly connected to both the front and rear sides of the interior of the hot press chamber 1. A top plate 11 is fixedly connected to the upper external side of the limiting rods 10. A pressing plate 13 that moves up and down is provided on the lower external side of the limiting rods 10. The outer wall of the pressing plate 13 fits tightly against the inner wall of the hot press chamber 1. A hydraulic rod 14 is fixedly connected to the bottom of the inner wall of the hot press chamber 1. The driving end of the hydraulic rod 14 is fixedly connected to the lower middle part of the pressing plate 13. Openings 12 are provided at both the front and rear ends of the top plate 11. Baffles 15 are fixedly connected to the front and rear ends of the top plate 11 inside the openings 12. The lower end of the baffle 15 passes through the front and rear ends of the pressing plate 13. A partition 16 for separating the materials to be pressed is provided inside the hot press chamber 1. An air passage hole is provided in the middle of the partition 16.

[0027] The hydraulic rod 14 drives the pressure plate 13 to move upward, which cooperates with the top plate 11 to press the material. At the same time, the external steam equipment is connected through the air inlet 23 to inject high-temperature steam into the hot pressure chamber 1. The upper end of the baffle 15 is provided with holes, and the middle part of the partition 16 is provided with through holes to promote the flow of steam and improve the pressing effect.

[0028] Working principle: The material to be pressed is placed on the loading plate 5, and the fixing pin 6 is placed between the unloading materials to be pressed to separate the upper and lower layers of material. The motor 21 is started to drive the threaded rod 19 to rotate. The rotating threaded rod 19 drives the threaded plate 20 to move to the left, thereby driving the loading plate 5 to move to the left. In cooperation with the push plate 22, the material to be pressed is driven into the interior of the hot press chamber 1. During the movement, the left end of the material contacts the end of the rotating plate 9 and drives the rotating plate 9 to rotate. After the material enters the hot press chamber 1, the spring 8 pulls the rotating plate 9 to return to its original position. Subsequently, the motor 21 drives the threaded rod 19 to reverse. This causes the feeding plate 5 to move to the right. Since the rotating plate 9 is blocked by the limiting plate 4, it cannot rotate outward, thus blocking the material and keeping it inside the hot press chamber 1. The feeding plate 5 returns to the upper right side of the bearing plate 2, making it easier to feed material from the lower side. The hydraulic rod 14 drives the pressing plate 13 to move upward, cooperating with the top plate 11 to press the material. At the same time as pressing, high-temperature steam is injected into the hot press chamber 1 through the air inlet 23 connected to an external steam device. The baffle 15 has holes at the upper end and the partition 16 has through holes in the middle to promote the flow of steam and improve the pressing effect.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
